Many Church leaders have identified the Holy Ghost as mortality’s greatest gift.

President Dallin H. Oaks said, “To have the continuous companionship of the Holy Ghost is the most precious possession we can have in mortality” (“The Aaronic Priesthood and the Sacrament,” Ensign, Nov. 1998, 38; Liahona, Jan. 1999, 44).

Elder Bruce R. McConkie taught: “Speaking from the perspective of eternity, eternal life is the greatest of all the gifts of God. But narrowing the perspective to this life only, the gift of the Holy Ghost is the greatest gift a mortal can enjoy” (“What Is Meant by ‘The Holy Spirit’?” Instructor, Feb. 1965, 57).

President Wilford Woodruff testified: “If you have the Holy Ghost with you—and every one ought to have—I can say unto you that there is no greater gift, there is no greater blessing, there is no greater testimony given to any man on earth. You may have the administration of angels; you may see many miracles; you may see many wonders in the earth; but I claim that the gift of the Holy Ghost is the greatest gift that can be bestowed upon man” (Teachings of Presidents of the Church: Wilford Woodruff [2004], 49).

And Elder David A. Bednar added: “The commandments from God we obey and the inspired counsel from Church leaders we follow principally focus upon obtaining the companionship of the Spirit. Fundamentally, all gospel teachings and activities are centered on coming unto Christ by receiving the Holy Ghost in our lives” (“Receive the Holy Ghost,” Ensign or Liahona, Nov. 2010, 97).
